<span style=''font-size: small''>I'm currently running an OS55AX with a 13x4 APC, it flies rather well with this engine. I would however like a little more power to pull out a little quicker from low altitudes, as I've been flying helis, parkflyers, and foamies and have gotten accustomed to flying in small areas and low altitudes.

I was thinking of trying an OS91FX or one of those ASP 4 strokes as they seem to have decent reviews. Not too mention they are fairly cheap and if I decide 4 strokes or nitro altogether is not for me I'm not out too much $$. I can just convert this UCD to electric.

Thanks for the replies guys, keep em coming.

How much does the UCD weight ready to fly?

For faster throttle response you might try:
Try a wood prop - Lighter so faster spool up
Also a good, fast throttle servo - HS 85mg

You can also comb the classifieds and ebay for a used saito. You can find deals out there if you know what to look for.
